Change the background color of the cells in a table column by creating a style and applying it to the table.

Create a figure with a table UI component in it and populate the table with numeric data.

fig = uifigure; fig.Position = [500 500 520 220]; uit = uitable(fig); uit.Data = rand(5); uit.Position = [20 30 480 135];

Table UI component with some random data.

Then, create a style with a specific background color and add the style to the second column of the table using the addStyle function.

s = uistyle('BackgroundColor','red'); addStyle(uit,s,'column',2)

Table UI component. The cells in the second column have a red background

Style cells in a table UI component that contain missing values. In this case, add a yellow background color style to cells that have NaN values.

Read tsunami sample data into the workspace as a table array. Then create a table UI component to display the data.

tdata = readtable('tsunamis.xlsx'); vars = {'Year','Month','Day','Hour', ... 'MaxHeight','Cause','EarthquakeMagnitude'}; tdata = tdata(1:100,vars);

fig = uifigure('Position',[500 500 750 350]); uit = uitable(fig); uit.Position = [20 20 710 310]; uit.Data = tdata; uit.RowName = 'numbered';

Use the ismissing function to get a logical array of the table elements that contain missing values. Find the row and column subscripts for the elements that have NaN values. Finally, create a yellow background color style and add it to the cells with NaN values in the table UI component.

styleIndices = ismissing(tdata); [row,col] = find(styleIndices);

s = uistyle('BackgroundColor','yellow'); addStyle(uit,s,'cell',[row,col])

Table UI component with tsunami data. Table cells that have NaN values are highlighted in yellow.

Create multiple styles and add them to different parts of a table UI component.

Create a figure with a table UI component in it and display numeric data in the table. Find the row and column subscripts for elements in the table with a value less than zero so you can style these cells later.

fig = uifigure; fig.Position = [500 500 720 230];

uit = uitable(fig); uit.Data = randi([-20,20],7); uit.Position = [20 30 680 185];

[row,col] = find(uit.Data < 0);

Create two background color styles and one style that specifies font color and weight. Add a cyan background color to columns 1, 3, and 5. Emphasize the cells with negative values by making their font red and bold. Then, style rows 3 and 4 with a green background color. Finally, reuse the cyan background color style and add it to column 7. For cells where multiple styles of the same type are added, the style that is added last is the one that displays in the cell.

s1 = uistyle; s1.BackgroundColor = 'cyan'; addStyle(uit,s1,'column',[1 3 5])

s2 = uistyle; s2.FontColor = 'red'; s2.FontWeight = 'bold'; addStyle(uit,s2,'cell',[row,col])

s3 = uistyle; s3.BackgroundColor = 'green'; addStyle(uit,s3,'row',[3 4])

addStyle(uit,s1,'column',7)

Table UI component with 7 columns and 7 rows. The negative-valued data is displayed in bold red text. Cells in rows 3 and 4 and between columns 1 and 6 are green. The remaining cells in columns 1, 3, and 5 are cyan. All of the cells in column 7 are cyan.

Create a tree to display a simple app hierarchy and highlight the different hierarchy levels.

Create a tree that represents the component hierarchy in a MATLAB® app. At the top level there is a UI figure window. The figure contains aUIAxes object and a Panel container. The panel holds a Button and a DropDown object. Expand all nodes of the tree to see the full hierarchy.

fig = uifigure('Position',[100 100 250 350]); t = uitree(fig); fignode = uitreenode(t,'Text','UI Figure'); pnlnode = uitreenode(fignode,'Text','Panel'); axnode = uitreenode(fignode,'Text','UIAxes'); btnnode = uitreenode(pnlnode,'Text','Button'); ddnode = uitreenode(pnlnode,'Text','DropDown'); expand(t,'all')

Tree that displays the hierarchy of a simple app.

Create three styles with background colors in different shades of blue to highlight the different tree levels. Apply the darkest background to the nodes at level one, a lighter background to the nodes at level two, and the lightest background to the nodes at level three.

s1 = uistyle('BackgroundColor','#3773EB'); s2 = uistyle('BackgroundColor','#78A1F2'); s3 = uistyle('BackgroundColor','#B5CBF8');

addStyle(t,s1,'level',1); addStyle(t,s2,'level',2); addStyle(t,s3,'level',3);

Tree that displays the hierarchy of a simple app, with different levels colored in different shades of blue.

Style nodes in a tree that showcases a file structure to visually distinguish different file types.

Create a tree UI component. Each top-level node represents a folder. Each child node represents a file in that folder. Expand the tree to see all the nodes.

fig = uifigure("Position",[300 300 350 400]); t = uitree(fig);

% Parent nodes n1 = uitreenode(t,"Text","App 1"); n2 = uitreenode(t,"Text","App 2"); n3 = uitreenode(t,"Text","Images");

% Child nodes n11 = uitreenode(n1,"Text","myapp1.m"); n21 = uitreenode(n2,"Text","myapp2.m"); n22 = uitreenode(n2,"Text","app2callback.m"); n31 = uitreenode(n3,"Text","peppers.png");

expand(t)

Tree with three top-level nodes with text "App 1", "App 2", and "Images", and nested nodes with file names.

Create three styles: one with a bold font weight, one with an italic font angle, and one with an icon.

dirStyle = uistyle("FontWeight","bold"); mStyle = uistyle("FontAngle","italic"); imgStyle = uistyle("Icon","peppers.png");

Apply the bold style to the top-level nodes to distinguish the nodes that represent folders. Apply the italic style to the children of the App 1 and App 2 nodes to distinguish the nodes that represent MATLAB program files. Finally, apply the icon style to the node that represents an image file to show a preview of the image.

addStyle(t,dirStyle,"level",1) addStyle(t,mStyle,"node",[n1.Children;n2.Children]) addStyle(t,imgStyle,"node",n31)

Tree UI component. The "App 1", "App 2", and "Images" nodes are bold, the nodes with file names that end in .m are italic, and the image file name has an icon of the image to its left.

Since R2023a

Create a list box with three items that represent different images.

fig = uifigure; lb = uilistbox(fig,"Items",["Peppers","Nebula","Street"]);

Create three styles with icons that correspond to the list box items.

s1 = uistyle("Icon","peppers.png"); s2 = uistyle("Icon","ngc6543a.jpg"); s3 = uistyle("Icon","street1.jpg");

Add the styles to the list box items to display the icons.

addStyle(lb,s1,"item",1); addStyle(lb,s2,"item",2); addStyle(lb,s3,"item",3);

List box UI component with three items. Each item has an icon to its left and text that describes the icon.

Since R2023a

Create a drop-down UI component with three items.

fig = uifigure; dd = uidropdown(fig,"Items",["Good","Fair","Poor"]);

Create three background color styles.

s1 = uistyle("BackgroundColor","#77AC30"); s2 = uistyle("BackgroundColor","#EDB120"); s3 = uistyle("BackgroundColor","#F77A8F");

Add the styles to the drop-down component items to change their background colors.

addStyle(dd,s1,"item",1); addStyle(dd,s2,"item",2); addStyle(dd,s3,"item",3);

The item background colors update, and the appearance of the component reflects the style of the selected item. The style does not change the color that displays when a user points to an item.

Drop-down UI component with three items. Each item has a different background color: The "Good" item is green, the "Fair" item is yellow, and the "Poor" item is red. The "Fair" item is selected and appears at the top of the component as yellow. The mouse cursor is pointing to the "Fair" item in the list, so that item is highlighted in blue.

Add a single style to both a check box tree and a table UI component to create a cohesive app appearance.

Create a figure window, and add a check box tree and a table in a grid layout manager. Populate both components with some sample data.

fig = uifigure('Position',[300 300 450 330]); gl = uigridlayout(fig,[1 2]); gl.ColumnWidth = {'1x','2x'};

tr = uitree(gl,'checkbox'); n1 = uitreenode(tr,'Text','Reptiles'); n11 = uitreenode(n1,'Text','Snake'); n12 = uitreenode(n1,'Text','Dinosaur'); n2 = uitreenode(tr,'Text','Amphibians'); n21 = uitreenode(n2,'Text','Turtle'); expand(tr)

tbl = uitable(gl,'Data',randi(100,[20 3]));

UI figure window with a check box tree and a table.

Create a style that specifies the font color, name, and weight. Apply this style to both the entire tree and the entire table.

s = uistyle('FontColor',[0.1 0.5 0.06], ... 'FontName','Calibri', ... 'FontWeight','bold'); addStyle(tr,s) addStyle(tbl,s)

UI figure window with a tree and a table. Both components use a bold, green Calibri font.

Input Arguments
